The present invention relates to a two-for-one twisting spindle with rotatably journalled hollow shank.

With two-for-one twisting spindles of the heretofore common type, the radially extending thread storage disc with overflow dish is driven, whereas the creel bobbin thereabove stands still. The threads are pulled off from the creel bobbin by a thread guiding means which in a rotating manner is ycarried along by the threads. The threads are then above the creel bobbin axially deviated downwardly and guided to the thread storage disc while a twist is effected. In the plane of the thread storage disc, the once twisted yarn is guided radially outwardly from the thread storage disc and is passed outwardly around the creel bobbin to a thread guiding member which is arranged axially above the creel bobbin. In this way lehe yarn obtains its second twist.

For purposes of securing a central journalling of the stationary creel bobbin, the latter is mounted on a bobbin carrier which by means of two antifriction bearings is rotatably journalled on a thread guiding pipe which is xedly connected to the overflow dish and rotates with the latter. F[The lower end of said bobbin carrier is located in the central plane of the thread storage disc so that for the exit of the yarn from the thread storage disc the deviation is effected radially outwardly around the marginal portion of said disc.

This design of a two-for-one twisting spindle is rather complicated and expensive because two relatively large antifriction bearings are required for journalling the bobbin carrier, said antifriction bearings extending around the thread guiding pipe. Moreover, diiculties are encountered in connecting the thread guiding pipe to the overflow dish as a result of which usually a plurality of individual members are necessary while the shape of the overflow dish is rather complicated. Thus, the overflow dish must have an axially downwardly directed bearing hub in which the thread guiding pipe is held because the end of said thread guiding pipe must freely extend up to the central plane of the thread storage disc.

, Other heretofore known two-for-onevtwisting spindles are simplified inasmuch as a rotatably journalled fhollow shank is provided on which the radially extending thread storage disc with overow dish is mounted. Above said disc with overow dish there is stationarily arranged the creel bobbin extending around the hollow shank. This Creel bobbin is by means of two bearings rotatably journalled on the outside of the hollow shank. Such an arrangement has the drawback that the bearings have to be of relatively great diameter or,if larger bearings are to be avoided, the hollow shank must be of rather small diameter so that it will be very sensitive to oscillations. In addition thereto, there is tlhe drawback that the bobbin carrier has to have an outer surface which precisely ts into the inner surface of the bobbin in order to assure a concentric seat. Thus, such an arrangement requires high precision work in order to allow the withdrawal of the bobbin from the bobbin carrier. The above arrangement has still a further drawback which consists in that the threading of the threads into the thread guiding members and through the thread guiding pipe including the thread brake provided therein can be effected only when the bobbin has been placed on the bobbin carrier. rDhe 3,299,623 Patented Jan. 24, 1967 ICC threading is particularly difficult because as a rule, twofor-one twisting spindles are provided with a so-called balloon limiting device which extends around the outside of the bobbin. The threading operation is also made difficult in view of the fact that within the balloon limiting device and outside the bobbin there has to be provided a protective basket in order to prevent the yarn leaving the thread storage disc and moving to the thread guiding member axially above the spindle from contacting the yarn body. The balloon limiting device on the other hand is necessary in order to prevent the thread balloon from swinging out too far.

It is, therefore, an object of the present invention to provide a two-for-one twisting spindle which will overcome the above-mentioned drawbacks.

It is another object of this invention to provide a twofor-one twisting spindle with rotatably journalled hollow shank which will make it possible to withdraw not only the yarn bobbin from the bobbin carrier but will also make it possible to withdraw the bobbin carrier with bobbin, thread brake and rotating thread guiding member from the spindle to thereby facilitate the threading operation prior to all elements occupying their working position.

It is still another object of this invention to provide a two-for-one twisting spindle with rotatably journalled hollow shank in which the creel bobbin carrier will be greatly simplified.

A still further object of the present invention consists in the provision of a two-for-one twisting spindle which will assure that the creel bobbin will automatically adjust itself and, more specifically, its centroidal axis, with regard to the axis of the two-for-one twisting spindle without running the risk that a non-centric location of the centroidal axis with regard to the axis of the two-for-one spindle brings about a unilateral load on the spindle and causes harmful oscillations.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:

FIG. 1 is a vertical section through a two-for-one twisting spindle with a bobbin creeel basket supported by a bobbin creel carrier.

FIG. 2 is an isometric view yof the bobbin creel carrier detached from the hollow shank and equipped with basket and thread guiding pipe.

FIG. 3 is a section similar to that of FIG. l of a twofor-one twisting spindle according to the present invention with a modified thread guiding pipe.

FIG. 4 is an isometric view of a bobbin Creel basket according tothe present invention.

The two-for-one twisting spindle according to the present invention which comprises a rotatable hollow spindle shank is characterized primarily in that at the free end of the hollow spindle there is journalled a creel bobbin carrier which is held stationary with regard to the rotatably journalled hollow shank, said carrier extending in a freely suspended manner toward the thread storage disc and surrounding said hollow shank with radial play. Thus, a hollow shank is provided which is stationary during the operation of the spindle and which extends as one piece over the entire spindle length while the creel bobbin carrier is exclusively supported at the upper end of the hollow shank, so that the hollow shank will be subjected to an axial load and not to a transverse load which could impart oscillations upon the rotating hollow shank. The standstill of the bobbin creel carrier with regard to the hollow shank can be realized, for instance, in the customary manner by providing the creel bobbin carrier with magnets having associated therewith stationary magnets arranged outside of the spindle and connected to the machine frame. With heretofore known two-for-one twisting spindles, the corresponding magnets are arranged, for instance, on the balloon limiting device which, in turn, is connected to the machine frame.

The invention may also be realized by rotatably journalling' a thread guiding pipe in the hollow shank, which thread guiding pipe extends approximately to the plane of the thread storage disc, while the creel bobbin carrier is connected to the free end of the thread guiding pipe which protrudes from the hollow shank. Also with this embodiment, the bobbin creel carrier is supported exclusively by the upper free end of the hollow shank, while the bearing body carrying said carrier is formed by a thread guiding pipe rotatably journalled in the hollow shank. This design has the advantage that the thread guiding pipe stands still and does not affect the twist of the yarn within the thread guiding pipe. With av rotating guiding pipe, the case may occur that the rotating walls of the thread guiding pipe impart upon the yarn during the twisting thereof an additional twist, which makes the twisting irregular.

Furthermore, it is advantageous that the creel bobbin carrier and the thread guiding pipe can together be disconnected fromy the hollow shank so that lthe yarn, after separating these parts, can be threaded through the thread guiding pipe. The yarn will then extend freely from the lower end of the thread guiding pipe. This protruding end will automatically, when inserting the thread guiding pipe, pass into the hollow shank into the plane of the thread storage disc and can readily be pulled out from the latter by means of a threading needle. This pulling out may, of course, also be effected pneumatically.

According to a further development of the present invention, the creel bobbin carrier may be detachably mounted on that end of the thread guiding pipe which protrudes from the hollow shank so that at any time the said carrier can, together with the bobbin, as a unit be detached from the hollow shank or from the thread guiding pipe.

In order to be able to bring about that when threading a thread through the thread guiding pipe, the latter will remain in the hollow shank, the present invention provides that the creel bobbin carrier carries a tube which extends in axial direction toward the thread storage disc, said tube being inserted from the top into the thread guiding pipe. Thus, if the thread is, outside of the balloon limiting device with a creel bobbin carrier separated from the spindle proper, passed through the tube, the yarn will automatically when mounting the creel bobbin carrier and when simultaneously inserting the tube into the thread guiding pipe, pass into the plane of the thread storage disc.

According to another embodiment of the present invention, it is also possible so to journal the thread guiding pipe that the thread guiding pipe can be moved out of the free end of the hollow shank and can be rotably journalled with regard to the hollow shank. With this embodiment, the thread guiding pipe is connected to the creel bobbin carrier and thus can be separated therefrom when it is disconnected from the hollow shank. Also with this embodiment, the threading operation is considerably facilitated. Also in this instance, a thread guiding pipe is involved which is at a standstill during the operation of the spindle and thus avoids the danger of imparting additional twist or even a counter-twist upon the yarn passing through the thread guiding pipe.

Referring now to the drawing in detail, according to FIGS. l and 3 the spindle rail 1 has connected thereto the hollow bearing shank 2 and, more specifically, by means of a bushing 3 and nut 4 which is threaded onto the thread 5 at the lower end of shank 2. Shank 2 is thus clamped between nut 4 and the shank shoulder 6 above the spindle rail, to the latter. Mounted on the hollow bearing shank 2 are two anti-friction bearings 7 which journal hollow shank 8. That end of shank 8 which is directly above spindle rail 1 forms a driving whorl. Hollow shank 8 extends upwardly to a considerable extent and above the whorl section is positively engaged by thread storage disc 9 with turntable 10. Thread storage disc 9 is fixed as to its location in axial direction by means of particularly wear-resistan|t yarn passing bushings 35 on shank 8.v To this end, bushings 35 extend radially into the hollow shank 8. Bushings 35 can easily be exchanged, if such should be necessary because of wear. However, the radial detachment of said bushings 35 suflices in order to permit withdrawal of the thread storage disc 9 with overllow dish 10 from hollow shank 8, in axial direction downwardly or upwardly.

According to a funther development of the present invention, the thread guiding pipe may at the upper end of the hollow shank be journalled by means of an axial bearing and may, above the thread storage disc, be journalled by means of a pure radial bearing, so that the thread guiding pipe can be detached or pulled out from the hollow shank while, during such a removal of the thread guiding pipe, the inner race ring including the cage of the antifriction bearing of that bearing which is located at said upper end of the hollow shank, will be removed. More specifically, the upper end of hollow shank 8 has arranged therein an anti-friction bearing 11 which comprises an outer race ring 12, a roller on body 13, and the inner race ring 14. Thus, there is formed an axial shoulder bearing so that the inner race ring 14 can together with the antifriction bodies 13 be withdrawn from the outer race ring 12 in axial upward direction.

In anti-friction bearings 11 there is journalled the thread guiding pipe 15 which extends downwardly up to approximately the central plane of the thread storage disc 9. The lower end of pipe 15 is journalled in hollow shank 8 directly above the needle bearing 16, and, more specilically in conformity with FIGS. 1 and 2 in such a way that the thread guiding pipe 15 may be axially withdrawn.

According to a further feature of the present invention, the bobbin carier may be equipped with an exchangeably connected basket as carrier for the bobbin, so that While maintaining one and the same bobbin carrier, it is possible, by means of the detachably connected bobin receiving basket to adapt the arrangement to the respective required bobbin size.

Thus, according to the present invention, the bobbin carrier may at the free end of the thread guiding pipe be designed in the form of a sleeve with a shoulder upon which a bobbin receiving basket may rest by means of an inwardly directed flange, and by means of a nut-like bushing may be clamped against said shoulder. Inasmuch as the bobbin carrier is provided with a downwardly extending bobbin receiving basket extending freely downwardly, there is no necessity to provide the bobbin carrier with precise seating surfaces tor the bobbin sleeve. Since, furthermore, the basket is not solid but forms a frame, it will be able, due to its elasticity, to adapt itself to the inner measurements of the bobbin sleeve and will assure a proper support therefor, While the bobbin carrier is supported exclusively by the upper end of the hollow shank and is rotatably journalled at said hollow shank.

More specifically with regard to the drawing, the creel bobbin carrier is screwed onto that end of thread guiding pipe 15 which protrudes beyond bearing 11. Carrier 17 is provided with a shoulder 18 upon which rests in axial direction a bobbin slip basket 19, by means of its ring 20. A cap 21 threaded on carrier 17 surrounds the latter. Within the basket 19 there is arranged a thread brake 22 which may be of any standard design and does not form a part per se of the present invention, so that no further details concerning said brake appear to be necessary. A thread guiding pipe 23 is screwed into cap 21 which is surrounded by a cap 24 holding at the lower marginal portion 25 the rotating thread guiding member 26. A

sleeve 28 with a yarn body 29 is slipped onto the inner legs 27 of basket 19.

According to a further development of the presentinvention, the bobbin receiving basket may consist of a ring adapted to be placed upon the sleeve and provided with at least three downwardly extending resilient U- shaped yokes While the ends of the other legs are interconnected by a thread ring. The bobbin is adapted to be placed upon the inner legs of said basket. In his way, a bobbin receiving basket is obtained which rests solely through the intervention of said ring upon the bobbin carrier designed in the form of a sleeve with a shoulder, and receives the bobbin, while the outer legs are interconnected by a thread ring. Thus, the outer legs together with the said ring form a protective basket for the thread which moves outside said basket and is passed from a lower portion of the spindle to au upper portion, and the yarn is prevented from engaging the outer edges of the yarn body so that thread breaks will be avoided.

Preferably, the inner legs of said U-shaped yokes extend in a downwardly flaring manner and/ or are curved outwardly, so that the bobbin will be seated on the legs with a certain preload. In view of the inclined location of the inner legs, or due to the curvature thereof, they have to be slightly elastically deformed when the bobbin is placed thereon, thereby also taking care of any slight deviations of the inner diameter of the bobbin sleeve.

As will be particularly evident from FIGS. 3 and 4, the bobbin receiving basket is formed by a ring 20 around which extend, for instance, four inner legs 27 of a Wire basket. Legs 27 are bent radially outwardly at their lower ends and then extend in a U-shaped form upwardly, so that the legs have a U-shaped contour.

As will be evident from FIGS. 2 and 4, the U-shaped form of the legs is obtained by the inner leg section 27, the radial leg section 30, and the outer sections 31. The ends of outer sections 31 are interconnected by a thread ring 32. In vieW of the inclined position of the inner sections 27 in cooperation with sections 30, bobbin receiving baskets 19 adapts itself to the respective inner diameter of sleeve 28 so that sleeves of diiferent diameters may be employed.

As will be seen from FIGS. l and 3, when the spindle is in operation, hollow shank 8 rotates, whereas the thread guiding pipe 15 with the basket 19 is at a standstill. To this end, as will be evident from FIGS. 1 to 3, magnets 33 may be arranged on legs 30 and these magnets may cooperate with counter-magnets stationarily arranged on the machine frame.

FIG. 4 does not show magnets 33 on basket 19 in order not to shroud the U-shape of the yoke of the bobbin receiving basket 19. However, if desired, it is also possible, similar to the arrangement of FIG. 2, to provide magnets 33 in the arrangement of FIG. 4 in basket 19. Such magnets may, if desired, interconnect adjacent yokes in such a way that the basket will be reinforced by the magnets.

FIG. 2 illustrates in detail those parts which can be detached from hollow shank 8 of the two-for-one spindle illustrated in FIG. l. More specifically, FIG. 2 shows the free length of the thread guiding pipe 15 which latter is provided with a seating surface 37 for bearing 11 and with a seating surface 38 for bearing 18. As has been brought out in connection with FIGS. l and 3, the thread guiding pipe 15 extends into the'carrier 17 to which is connected a bobbin receiving basket 19. Furthermore, FIG. 2 illustrates cap 24 on which the thread guiding member 26 is mounted.

As will be seen from FIG. 2, yarn body 29 arranged on sleeve 28 may, together with said sleeve, be placed on basket 19 in a disconnected condition with regard to the rotating pants of the two-for-one spindle. The mounting as well as the threading may be effected outside the machine. The said thread is passed from the top through thread guiding pipe 23 in axial direction through thread guiding pipe 15 which protrudes from the lower end of thread guiding pipe 15. If prepared in this way, the parts illustrated in FIG. 2 may, as a closed unit, be placed upon hollow shank 8 while the thread guiding pipe 15 is inserted into hollow shank 8 and journalled in bearings 11. With this insertion, the free thread end protruding from the thread guiding pipe 15 will be located in the central plane of the thread storage disc 9. The thread may then radially from the outside be passed through one of the yarn bushings 35 into the thread` storage disc 10 and, more specifically, will be passed upwardly through the overow dish. Thus, the threading and preparation of the twisting operation are considerably facilitated while it is advantageous, in this connection, that the said preparing operations can be carried out outside the twisting machine.

The employment of a helical threading device will be obviated which, with heretofore known two-for-one twisting spindles has to be passed from the bottom through the entire thread guiding pipe in upward direction in order, at this area, to grasp the thread. The arrangement of the two bushings 35 located along a diameter line will permit a pneumatic threading of the yarn through the twist passage bushing 35. If a certain length of the yarn extends downwardly and protrudes from the thread guiding pipe 15, the said yarn length can be drawn outwardly.

In contradistinction to FIGS. 1 and 2, the arrangement according to FIG. 3 is such that the bobbin carrier 17 is detachably mounted only on the free end of a tube 34. Tube 34 extends partially supported on the inner wall of thread guiding pipe 15, with play through thread guiding pipe 15, and has its inner wall surface covered with synthetic material 36 as, for instance polyethylene, in order to improve the free passage of the yarn inasmuch as through said synthetic material the yarn will be subjected on the inner wall surface to very minor friction. Also with lthe embodiment of FIG. 3, the bobbin carrier 17 can be axially lifted olf and it is merely necessary to pull tube 34 out of the thread guiding pipe 15. Thread guiding pipe 15 will thus, with this embodiment, remain at its place and will not be disengaged. However, inasmuch as tube 34 extends through thread guiding pipe 15 and since tube 34 forms an inner thread guiding pipe, the threading operation can be effected in the same manner as described above in connection with FIGS. l and 2. This embodiment has the advantage that when disconnecting the bobbin carrier 17, the thread guiding pipe 15 remains in hollow shank 8, so that bearings 11 and 16 remain covered.

Itis also possible, with the embodiment according to FIGS. l and 2, instead of screwing bobbin carrier 17 upon thread guiding pipe 15, merely to slip on said carrier 17 so that the latter canbe lifted olf together with the basket without simutlaneously disconnecting the thread guiding pipe 15 from the hollow shank 8.

It is, of course, to be understood, that the present invention is, by no means, limited to the particular arrangements shown in the drawing, but also comprises any modifications within the scope of the appended claims.
